I had a problem to figure why my click didn't pass through the DefaultWindow ... and finally found the MousePassThroughEnabled Property on your forum
I write a little post because there is some strange behavior that drive me toward bad conclusion.
When the MousePassThroughEnabled Property is disable, I can make the click Pass Through by double clicking ... and I really wonder why it's working
So my problem is fixed until the next one
